Abstract:
Background Surface disturbance caused by production and construction projects is the main source of soil and water loss caused by human activities. In China, 25, 000 to 30, 000 soil and water conservation projects are approved every year. The competent departments of the industry mainly obtain the relevant information of the projects through paper reports, and the supervision tasks are large and the monitoring data acquisition lags. The purpose of this study is to use new technical means to assist the monitoring of soil and water conservation, improve the efficiency of supervision and management of soil and water loss in projects and the accuracy of monitoring data, and reduce the soil and water loss caused by man-made construction activities.
Methods In this study, Ovital map, CAD, ArcGIS software and mobile terminals loaded with Ovitalmap were used to carry out soil and water conservation monitoring for production and construction projects. The technical path was divided into four aspects, which are the project area soil erosion background investigation, soil and water conservation monitoring during the construction period, daily monitoring data management, water and soil erosion hazards emergency response.
Results Compared with no Ovital map, this method: 1) improved the accuracy of soil and water loss background survey data in the project area, and the data could be shared with other members in real time to carry out related work simultaneously; 2) it can quickly anticipate the area prone to soil and water loss in the construction process, so as to facilitate monitoring and improve work efficiency and monitoring results accuracy; 3) Ovitalmap, as data reported to management platform, facilitates the competent departments to carry out daily supervision and management; 4) Using maps to verify remote sensing results can improve the disposal efficiency of soil erosion hazards.
Conclusions The use of Ovitalmap to assist soil and water conservation monitoring is beneficial to quickly and accurately obtain soil and water conservation monitoring data of production and construction projects, to improve work efficiency and data accuracy, and gradually realize the "one map" management of various topics with the help of this method, to provide diversified supervision and verification methods for the supervision of industry authorities, and provide an open participation platform for the masses to participate in and supervise the soil erosion of projects. Finally, it can improve the efficiency of supervision and management of soil and water loss in production and construction projects and reduce soil and water loss. Some functions of Ovitalmap require users to pay fees, and the map has weak statistical summary and overlay analysis of geographical factor attribute data, so it is recommended to optimize.
